IVIAILING IRECEPTAGLE.

Application filed August as, 1920. Serial No. 405,347.

T 0 all whom it may concern:

Be it known that I, JOEL E. I-IAwLnY, a citizen of the United States, residing at Kansas City, in the county of Jackson and State of Missouri, have invented certain new and useful Improvements in Mailing Receptacles; and I do declare the following-to be a full, clear. and exact description ofthe inventiomsuch as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon. which form a part of this specification.

This invention relates to a container adapted to be utilized for use in saving fine particles which are ground from precious metals.

The invention is particularly applicable for use in receiving the ground-off gold of artificial dentures during the process or" making the same. For example, dentists usually shape-up the artificial dentures, such as gold inlays, crowns, bridges and the like, by a rotary burr disk or similar tool, with the result that there is considerable waste gold ground from the artificial denture.

It is the purpose of my invention to provide means whereby such gold may be collected in a suitable receptacle, which may be closed and mailed direct to a refiner so that the gold may be recovered to again be used.

In carrying out my invention I prefer to construct the receptacle of a destructible material, preferably cardboard, the receptacle being formed from a blank properly scored so that the side and end flaps may be bent up to form a trough-shaped receptacle to be supported by the operator in a convenient manner. The construction of the receptacle is such that it may be subse quently so that the receptacle and its contents may be mailed to a refiner who, in recovering the gold, may cause the envelope to be consumed whereby liability of any of the gold becoming lost will be prevented.

The feature of providing the receptacle of a destructible material is important to the extent that it insures the recovery of all or the gold although my invention contemplates certain other features, such as the construction of the device, which are not necessarily dependent upon any particular material.

collapsed in the form of an envelope an upwardly inclined In the drawings,

Fig. 1 is a perspective view of the receptacle ready to be applied.

Fig. 2 is a perspective view oi the blank.

Fig. 3 is a perspective view of the receptacle collapsed for mailing, and

Fig. 4 is a view showing the device in use.

The form or" device selected for illustration consists of a blank comprisinga main body portion 1 having a bottom flap 2 and a bottom flap extension 3, the combined lengths of the bottom flap 2 and its extension 3 being slightly less than the length of the main body portion 1:, both the flap 2 and its extension 3, however. are substantially the same width as the main body portion 1.

The main body portion 1 provides a sub other precious metal within the receptacle,

while the end or bottom portion 2, folded along the score line 1, constitutes an end wall to arrest the gravitation of the gold or other precious metal within the receptacle, the extension 8 being folded back upon the endZ in actual practice.

The upper end of the body portion 1 is provided with an end flap 5 having a foldedover edge 6 to add stability thereto and to enclose the end" extension tabs 7 and 8, carried by the upper ends of the side flaps 9 and 10, which extend the entire length of the body portion 1 and which are folded at right angles thereto along the lines 12 and 13. a

The outer edges of the flaps 9 and are outwardly curved toward the end flap 2 and they are provided with diagonal score lines 14L and15 whereby the ends 16 and 17 may be folded inwardly "to provide upwardly inclined edges in the finished product, against whichthe end fiap 2 may rest so that the finished receptacle is provided with bottom to provide a hopper-like structure and thereby the fine particles of gold may be directed into the hopper-like portion 18 of the receptacle.

The wider portions 19 and 20 at the lower ends of the flaps 9 and 10 are provided with slots 21 and 22 for the flap 9 and 23 andQ I for the flap 10, the slots 21 to 2d inclusive being adapted to receive the tongues 25, 26, 27 and 28 on the side flaps 29 and 30, carried by the end'flap 2 and folded along the lines 31 and 32.

When the blank is formed as above described, the side flaps 9 and 10 may be told ed at right angles to the body portion 1, the end flap 5 may be folded at right angles to the body portion 1, and the extension 6 folded over the tabs 7 and 8 to provide rigidity for the finished structure at the up perend thereof.

The side flaps 9 and 10 preferably have reinforced openings 33 and 34: near their upper edges, through which a loop or sling 35 may pass to permit the receptacle to be suspended from the neck or shoulders of the operator.

If the side walls 9 and 10 are folded at right angles to the body portion 1, the angular portions 16 and 17 are folded along the lines 21 and 22. Then the bottom or end flap 2 is folded against the inclined edges of the flaps 8 and 9 and the extension 3 is folded down over the end 2, preferably over the strip or extension 36 on one of the flaps 9 or 10. The tongues 25 to 28 are then inserted in the slits 21 to 24 inclusive and the device is ready for use.

The operator holds the denture in the open space 37 or adjacent thereto and operates the grinder to grind OK the material,'

which will gravitate into the receptacle where it may be collected. After a sufficient amount has accumulated in the receptacle, the tongues 25 to 28 may be released from the slits and the side flaps 9 and 10 folded inwardly, as may also the flaps 5 as well as the flaps 29 and 30. Then the end portion 2 with its extension 3 is folded over the flaps parallel with the body portion 1 and the ends of the extension 3 may be secured to the body portion by suitable fastening devices as, for example, the clips 38 and The package is then ready for mailing to the refiner.

As heretofore indicated. I prefer to construct the blank of perishable material as this makes it possible to place the receptacle unopened in a crucible or oven so that the heat will destroy the container and leave the free gold to be recovered. However, it is not absolutely essential that the receptacle be made of perishable material as it is possible to invert the receptacle to dump out the collected gold if desired, although the latter method is not so advantageous as the former.

From the foregoing it will be apparent that a device constructed in accordance with my invention can be cheaply manufactured, that it is adapted to receive the fine filings or grindings from precious metals and the like or wherever it is desired to save the ground-off material in a. rinding or filing operation. and that the recovery of the collected material may be easily accomplished.

It will also be apparent that the dentist may place the sand paper grinding disks or other grinding tools in the receptacle before collapsing it and thereby save additional gold since some of the gold will adhere to the disk during the grinding operation.

In order toinsure all of the gold being saved, it is recommended that the package be placed in a strong envelope before mailing so that in the event that any of the gold sifts through the package, it will be held in the envelope.

What I claim and desire to secure by Letters-Patent is:

1. A receptacle blank comprising an elongated, rectangular body portion scored to form an end wall of substantially the width of the body portion, a foldable extension on the end wall substantially the width thereof, a relatively narrow end wall at the other end of the body portion, a foldable extension thereon, side flaps extending substantially the length of the body portion and of progressively increasing widths toward the first named end wall, diagonal scoring lines at the wider portions of the side flaps to permit the corners to be diagonally bent with respect thereto, the side walls having tongue-receiving slits, and the side walls on the first named end wall having tongues for engaging the slits of the first-named side walls.

2. A device of the class described formed from a single blank comprising a rectangular body portion, side flaps, an end flap, a foldable extension on the end flap, separate side flaps for the end flap, foldable corners on the first named side flaps. and means on the second named side flaps for interlocking engagement with the first named side flaps whereby a receptacleis formed with an elongated front open portion to receive material thereinto.

A device of the class described for re ceiving fine particles which are ground from precious metals comprising an extensible and collapsible receptacle. the receptacle when extended having a substantially vertical openingto receive the metal ground off, and when collapsed, constituting a mailing envelope by means of which the metal can be transported through the mails.

1*. A device of the class described for receiving fine particles which are ground from precious metals comprising an extensible and collapsible receptacle, the receptacle when extended having a substantially vertical opening to receive the metal ground off. and when collapsed, constituting a mail ing envelope by means of which the metal can be transported through the mails, the receptacle consisting of destructible material whereby the receptacle can be burned away from the contents to reclaim it.

In testimony whereof I afiix my signature,

JOEL E. HAWLEY.
